Spark plug wires (leads) from many 4-cylinder engines will the Datsun 1200, although the wires might be a little long. It is easiest to buy a set specifically for the B110's A12 engine.

Overview
- Resistor type wires are recommended to prevent radio static.
- Large diameter wires (8mm, 9mm, etc) will have no effect unless you are running a non-stock high-energy ignition system.
Inspection
You can test the spark plug wires, they last for decades.
- One by one, remove a wire from the cap. If the metal end is corroded, yet the other plug wires look good, that indicates the cylinder is not firing correctly.
- Check the spark plug wires with an ohm-meter. It should read somewhere around 1,000 ohms per inch
- If a plug wire reads 0 ohms, or much lower than the others (per length) it is bad
- Replace those wires that are bad. Looks for burns, cuts, bubbles or detached metals ends
Likewise inspect the cap & rotor. Mine are 30 years old still working perfectly.
- You can carefully scrape the metal contacts inside the cap to bare metal
- Scrape the edge of the rotor to bare metal
- Look for burn marks inside or out, look like black scratches. Replace if any are found.

For example, each set for B110 fits several other engines. It probably depends on exact how the manufacturer cut the wire lengths.
